Yes there is smoke from the exhaust and it does use a bit of oil too.

Thats my engine and all the pipe work and hoses are all hooked up to the factory places. The second pic is the pipe in question where the oil is leaking. I think its the one that goes down the smic?

Picture shown is not of my engine bay but shows the pipe in question.

I have a R33 which is pretty much stock. It runs the standard turbo with the standard intake piping. I've noticed that it is leaking oil from the location indicated with my awesome arrow. Can someone tell me why it would be leaking oil from there please?

Where the f**k have you been?

So it could be cracked studs, leaky exhaust gasket or a crack in the manifold?

I'm getting around 500km's per tank. I got the studs replaced 50,000kms ago. So there would be a exhaust leak at the manifold if they had broken?

Huh? Do they snap off over time? Is that what you are saying? Or are you saying that they snap when you change the manifold? If this is happening wouldn't I hear a exhaust leak on the manifold itself?

A couple of months ago with those iridium plugs.

If it is the closed throttle signal, how would you check that?

The exhaust was on the car since I bought it and it never used to have this popping issue that bad. I'd probably go the 3 inch and then get a decent resonator. That should give you the drone your after.

From inside the car it's not that loud. I run the stock manifold with 4 inch dump and 3.5 system, highflow cat and a drager cannon. I have been told that when you get on it it is a tad rumbly from outside I was going to put a different cat on it to make it even louder but then you would get that droning noise through the car Car runs fine. Only draw back is you can't have the car to low because of the zorst. I've been told that it sits higher than most 33's.

Recently I have noticed a increase in the volume of the popping and sometimes cracking noise from my exhaust when I'm de accelerating. What could cause this? The engine is stock with stock intake it has the usual 3.5 inch exhaust with cannon and a high flow cat. I haven't changed anything on the car but have been told that my oil rings could be stuffed. Would the popping noise increase due to worn rings? Also if your turbo is on it's way out, would this increase the pops? It used to do it when it was over due for a service then when it got serviced it would go away. Anyone have any ideas? I'm stumped.

You could also try lumleys they are cheaper than shannons and offer the same.

Looks like a 1.5
